I am working on an engineering project. I have a CPU wirelessly connected to an Arduino Uno R3. The CPU receives user input and sends it out to the Arduino, which stores the data in an EEPROM memory location. The data is modified within the Arduino and subsequently sent out to an external circuit where it will undergo a D/A conversion (allowing the data to be viewed on an oscilliscope).

How can I send the data (approximately 500 bits) from the 12 EEPROM memory locations to the output pins of the Arduino?
